Overview of S-400 and S-500 Air Defense Systems
The S-400 Triumf, known as Sudarshan Chakra in India and SA-21 Growler to NATO, is a mobile surface-to-air missile (SAM) system developed by Russia’s Almaz-Antey. Deployed since 2007, it can engage aircraft, drones, and cruise missiles up to 400 km away. The S-500 Prometheus (SA-23), introduced in 2021, is Russia’s next-generation system, targeting advanced threats like hypersonic missiles, intercontinental ballistic missiles (ICBMs), and low-orbit satellites, with a range of 600 km and an altitude of 200 km.
- S-400: A versatile defender against a wide range of aerial threats.
- S-500: A specialized sniper for high-speed, high-value targets, including near-space assets.
Both systems are mobile, modular, and integrated into Russia’s layered defense network, but their roles differ significantly. Which one sounds more impressive to you? Share your thoughts in the comments!
